CLOSURE DEVICE FOR CONTAINERS.

Application nled December 11, 1925. Serial No. 74,786. i

" This invention relates to closure devices for containers, and particularly to that class of closures which includes a dipper for removing a portion of the contents of the container.

At present it is common to mount a rigid clipper, such as a glass rod or dropper, in a resilient closure such, for instance, as a cork stopper, so that when the stopper is in place in the container the dipper will project into the contents of the container, and when the stopper is removed the clipper Vwill be removed with it and will withdraw a portion ofthe contents from the container.

Invorder to effectively close the container, however, it is necessary to force the stopper into the mouth of the container until the stopper becomes compressed to such an extent that the reactive force developed will maintain the stopper in place because of the friction between the stopper and the contacting portion of the container. Y

Inasmuch as the Stopper not only acts as a closurefor the container, but also as a handle for the dipper, it is necessary to extract* the stopper from the container in such a manner that it will not be destroyed or materially weakened. Because ofthis fact it is impracticable to use stopper extracting devices which penetrate the stopper, and it is, therefore, the usual practiceto extract the stopper by applying a transverse as well `as a longitudinal force to the stopper, developing a rocking motion as well as a withdrawing motion. This rocking motion ofttimes results in the dislocation or, when the clipper is of fragile material, in the breaking of the dipper whichthe stopper carries.

The present invention has for its object to so mount the dipper within the stopper that 'the usual rocking and withdrawing actions will not result in the dislocation or fracture of the dipper, with the result that the stopper and rod will maintain their original assembly throughout use. i

I have illustrated one form of the invention in the drawings, in which Y Figure 1 is a longitudinal, sectional view showing the stopper in place in a bottle;

Figure 2 is a transverse, sectional view on the line 2-2 of Figure l; and

Figures 3 and 4 are sectional views of modifications of the device.

For illustrative purposes I have shown the application of the invention to a bottle stopper, but I do not wish to be limited to this' use, for :it is obvious that the invention may be used in connection with other types of containers.

The embodiment of the invention illustrated includes a compressible stopper 1lv which has sufficient resiliency so that when it is forced into the mouth of the container' it will be held in such posit-ion by the friction developed between the stopper and the contacting portion of the container. e

While cork is an admirable material for the stopper, it is obvious that other materials lpossess the same qualities and the invention is, therefore, not to be limited to the use of any particular material.

The stopper l is provided with a recess 2 which may extend partly or completely through the stopper, and may be of any desired transverse cross sectional configuration, the recess in the drawing being disclosed as circular in cross section merely for the sake of convenience of illustration.

A similarly shaped socket member 3 is mounted within the recess 2, and is rigidly secured therein by suitable `means such, for instance, as by an adhesive. This socket membercarries a dpper 4 which in the form illustrated in the drawing is 'a glass rod, the rod being suitably attached to the socket member as, for instance, by extending into a recess 5 in the socket member, and being secured therein in any suitable manner, such asby frictional engagement or by means of an adhesive. Y

The material of the socket member is relatively rigid and non-compressible, so that the forces applied to the resilient portion of the stopper are repelled by the socket member and are, therefore, not transmitted to the dipper. It has been found that wood serves admirably as a material for the socket member, but obviously the range of material is wide and the invention is not to be limited to the use of wood. The result of the repelling of these forces by the socket member or sheath 3 is that the dipper will not be subjected to the forces and consequently the possibility of dislocation or fracture will b entirely obviated. p Moreover the location of a relatively rigid socket member within the stopper results in the formation of a core which tends to pre vent the breaking of the stopper as it is being extracted from the container.

so e

While I haveillustrated a .particular embodimentfof the invention, I do not wishlto be limited to that embodiment as it is obvious that many changes in the details of construction may'bemade Within'the scope of the claims.

In the modification shown in Figure 3 the dipper is extended completely through 'the cork 6, and extends beyond the upper end of the cork as at 7 being secured in the cork kbysuitable means such `as byan adhesive.

The purpose offthelextension ofthe portion -7 ofthe dipper beyond the-end of the cork is so that this portion of the dipper may be Lused as a. grip, by means of -which-the cork lmay-be extracted ywithout injury, such as `often `occuis when the cork is soaked or 'soggy,or1when it=issubjected to the action otra corkscrew.

V"Itisiofcourse to berealized that the portion of the dipper which extends into the container in the construction shown in Figure B'may be omitted, leaving only that portion which is `secured Within the cork and Vthat portion whichi'extends beyond the end -vided with an enlarged portion 9 which is adaptedto engage-the lower end of the cork andpreventany tendency of the dipper rod tolpull through the cork. Of course in this easethat portion of the dipper rod which is located Within the cork may be, if desired,

Asecure-dto the cork as for instance'by an adhesive.

Moreover, if it is desirable to omit the portion of the dipper which extends into the container from `this construction, this may be done leaving only the enlarged portion 9 and that portion which extends through and beyondlthewok. VhatIlclaim-is: f f

Y 1. A stopper comprising a tubiform body made Vfrom resilient material with a longitudinal bore opening through ends thereof, and a force resisting core entirely filling the boreand permanently fixed within the body fromend to end of the same, said core being flush with the ends ofsthe body, anda di per having one-end embedded in-the core or Va distance less than the len 4th 'thereof'with the engaged -end of the dlpper completely.

surrounded snugly `by the core.

`2. A stopper comprising a tubiform'body made from resilient material `with a longiybeing vflush with the ends of the.`body,a'nd

a dipper having one end embedded 1n 'the core for a distance less than the lengthfthereof with the engaged end of the dipper completely surrounded snugly bythe core, said body at its initial engaging end being tapered.

3. A stopper comprisinga tubiform-body made from resilient material, a force resisting core embedded in said'body,and a dipper of fragile material extending`from`lsa1d body and having its end embedded in said core, theengaged endbeing completel surrounded snuglyl by the core and entire y out of contact with the resilientmaterial'of'the body. y

In testimony whereof, I have signed my name .to this specification this ninth day of December, 1925.
